2 : 1 : 1
12 of the remaining amount is the same as
25 of the total amount.
Amount that Adam has at first = 5 u
Amount that Adam spends on the stickers
= 3 u - 2 u
= 1 u
1 u = 220
Amount that Adam has at first
= 5 u
= 5 x 220
= $1100
(b)
Amount that Adam spends on marbles
= 2 u
= 2 x 220
= $440
Amount that Adam spends more on marbles than on stickers
= 440 - 220
= $220
Answer(s): (a) $1100; (b) $220
